Residual Solvent Analysis

Back to Homepage

Concentrates and tinctures are analyzed for harmful concentrations of residual solvents including: Butane, Pentane, Hexane, and Isoproponol. These results are reported using our Gas Chromatograph (GC) in parts per million (ppm). By utilizing these results and the USP 467 Residual Solvent standard we can determine the consumption safety of your medicine.

Current Thresholds Propane         – 500ppm Isobutane      – 500ppm Butane           – 500ppm Isopentane    – 500ppm Pentane          – 500ppm Hexane           – 280ppm Methanol       – 300ppm Ethanol          – 500ppm Acetone          – 500ppm Isopropanol   – 500ppm
